I do not buy the concept of sin. We all have flaws; who has the authority to tell me that any of my flaws are sins, or even define my flaws for me other than in a legal or physical context?
Among my flaws are impatience and selfishness. Among my virtues are a talent for analogical thinking and a generosity that I try to allow to override my selfishness. Perhaps I am fooling myself and what I think and hope is generosity is really just an eagerness to share, not for altruistic reasons, but simply because I long to be understood, which would explain why I am taking the time to answer all these questions.
